We got 6 to 7 inches of water (uneven basement floor) so a lot got damaged...

The speakers are still fine sound-wise but the case swell up.

Skipping the center seems worse to me than skipping the sub. Are the M60s as good at covering bass as the M80s? I could save by going with the M60s but if the bass is lacking, then I would need the sub... I can either spend 800$ to get the sub or 400$ extra for the M80s...
